C.  aFarmers? knowledge and perceptions of earthworms in agroecosystems of La Vieja watershed in Colombia.  c2008  aColombian farmers were interviewed to investigate their knowledge and perception about the relationship with the soil and agroecosystems quality and earthworms. In the study a map was chosen, with a non probabilistic random systemic design, nine windows of one km2 with 16 testing points at 200 m distance inside each window in the La Vieja watershed. In the collection of data were interviewed 30 farmers and oral history was considered with questions about environmental systems of support and culture. Farmers? ability to recognise different use for earthworm and was significantly influenced by their length of experience in appraising good condition of soil and association with the colour, some indicator plants, and best state of the nutrients but a lot of species were not identified, ecological category or the nutrients cycle of soil. Most farmers (81%) were aware of the level of profit and production of crops and the soil characteristics, in their farms separating the land for soil condition and abundance of earthworms are very important for this prognostic. The local human communities determine the level of avail and land use. This study shows that is necessary to establish a common language between scientific and farmer communities with the interaction of local knowledge and experts. This article discusses two images of the importance including the ideas that are complementary rather than contradictory.
